This study examines the effects of firm-specific factors on the short-run and long-run returns of Indian initial public offerings (IPOs). This research adopts the robust least-squares method to investigate the relationship between shortand long-term returns of IPOs and firm characteristics. This study examines hand-collected data for 328 IPOs over a period of 10 years to identify factors that influence the long-term and short-term performance of IPOs. The findings confirm that the issue price, age, and size have a significant and positive influence on the short-term performance of IPOs. Furthermore, the timing of IPOs has a negative impact on short-term performance. We also find evidence that short-term, market-adjusted excess returns have a positive effect on long-term returns. The findings of this study help to build an understanding of firm-specific factors that may be used to forecast IPO performance in the Indian context
